VJhen these bands are. made separately and not as a thickened portion of the protective coating, they may be either fastened to the inner wall of the containing vessel or fastened in position around the elements or simply held in position by friction with either the elements or the containing cell Walls or hoth. Figures 1 and 2 show the condition of the protecting hands being held inside the containing ressel, While. Figures 3 and 4 show the bands placed around the elements prior to the placing inside of the containing vessels.

Without enun'ierating equivalents and Yariations, I claim as my invention:

1. A battery container made of nonacid resisting material and covered with a pyroxylin plastic; said pyro'xylin plastic being thickened over certain predetermined areas.

A battery container made of nonacidresisting material and covered with a film of an impervious acid-resisting substance, said .'im heing throughout adhesive to, and integral with, said nonacidaesisting material, and protecting strips of acid-resisting material on the inner walls oi": said con" tainer.

3. A battery container made of nonacidresisting material c ated with a film of a pyroxylin plastic, said film being uniformly adhesive to. and integral with. said nonacicl-resisting material. and a protecting strip of acid-resisting material on the inner wall of said container.

L. A battery container made of nonacidresisting material coated with a film of a pyroxylin plastic, said lihn heing throughout adhesive to. and integral with. said nonacid-rcsisting material, the thickness of said pyroxylin plastic being increased over certain predetermined areas. where the battery elements are said areas.
